It took Warren Buffett almost nine years after the first iPhone was sold to pull the trigger on buying Apple inc.’s stock. After nearly three years of rapidly building his stake, Thursday’s stock selloff has likely put his investment underwater.
Based on 13F filings with the Securities Exchange Commission, Buffett’s investment vehicle Berkshire Hathaway Inc.

That was about a year after Apple joined the Dow Jones Industrial Average and a little over three years after Apple resumed paying a dividend. The first iPhone was launched in June 2007.
Since then, he’s increased his stake to 252,478,779 shares, or about 5.3% of the shares outstanding as of Sept. 30, 2018, enough to make him the second largest shareholder. At that time, Buffett’s investment in Apple was valued at about $57 billion, not including dividends.
The stock has now plunged 38.7% since closing at a record $232.07 on Oct. 3. Over the same time, the Dow DJIA, +3.29% has shed 4,142 points, or 15.4%.
At current prices, the value of Buffett’s stake, assuming it has remained the same size since Sept. 30, would be down about $4 billion on the day, and $21.1 billion since Sept. 30.
